1800°C U-Shape MoSi2 Heating Element for Dental Furnace
MoSi₂ (Molybdenum Disilicide) heating elements are high-performance resistance elements made primarily from pure molybdenum disilicide. When exposed to an oxidizing atmosphere at high temperatures, the surface forms a protective quartz film that prevents further oxidation. These elements are ideal for high-temperature applications ranging from 500°C to 1800°C, including sintering and heat treatment in ceramics, magnets, glass, metallurgy, and refractories.
MoSi2 heating elements are brittle at room temperature but become ductile at high operating temperatures. The recommended installation method for U-shaped elements is vertical suspension from the furnace top using specialized support clamps. This approach prevents mechanical stress from concentrating on the heating zone of the element, significantly reducing the risk of fracture and extending service life.
Key Installation Requirements
Support Clamp Selection: Specific support clamps are designed for different element sizes (e.g., 6/12 and 9/18 types)
Precise Alignment: Clamps must be carefully installed to ensure perfect vertical positioning
Proper Insertion: The tapered lower end must fully extend into the furnace chamber to prevent localized overheating
Weight Distribution: Support clamps must bear the entire element weight while maintaining secure positioning
